My Xamarin Android application is ready, people download it from a Google game, and everything seems fine, except that from time to time I get the following errors in the Google Play developer console:
java.lang.RuntimeException: Unable to instantiate application mono.android.app.Application: java.lang.ClassNotFoundException: Didn't find class "mono.android.app.Application" on path: DexPathList[[],nativeLibraryDirectories=[/vendor/lib, /system/lib, /vendor/lib]]

or a similar but slightly different version:

I have Google null results for ClassNotFoundException + mono.android.app.Application. According to the developer's console, it comes with Android 4.2 and 4.4., Various devices (HTC, Samsung ..), even from devices that I tested and everything works (HTC One).
Any ideas? Is this a bug in mono? or xamarin? Or am I doing something wrong?
